There were many emails & calls from iPhone users around the world, who have written to me  and enquired about dozens of questions, who did not have much of technical depths of iPhone & iOS  functionalities. Also some of the latest technical features of iPhone 4 &  iOS 4.0 version releases, such as running applications in background, Bringing back such Application to foreground/screen, Doing search of Apps, Contacts, Music, Notes, Accessing iPod & playing music using  Home button (Pressing home button Twice > Applications  those are running in background are displayed> do right swiping till you get iPod Buttons).

As I have been enjoying answering to such basic facts & tips to use iPhone effectively, I am willing to help such iPhone users from round the world to write to me on my e.mail address devarajan at gmail.com with following questions.

1) Your Problem in Single Line
2) Explain about the problem in detail with the app name(iPhone default apps)
3) Write the iOS version  Home > Settings > General > About
4) Model Number
5) Screen Shots of the error(To take a iPhone Screenshot), Press “Home” & “Power”  button Simultaneously/Both Together, you would hear a sound like a camera snap. Go to Images folder and see the screenshot and email

I swear, I will not ask for any paypal donations or service charges for the support I would like to give for basic problems which are related to using the basic usages of iPhone.
